I use an F hook, a K hook, a yarn needle to weave in the ends and sew the pieces in place, and Red Heart Super Saver Yarn. I’ve added the sunflower pattern below for the summertime rooster charm shown above as well. Both roosters are done with the same pattern and different colors.

~Hollow Shamrock~

With an F hook:

Rnd 1: Ch 2, (sc, ch 10) three times into 2nd ch from hook. Sc again into the hook. Jn with a sl st in first sc.

Rnd 10: Along each leaf of 10 chains: Sl st 3 times, (sc, hdc, sc) into the next ch, sl st in next 2 chs, (sc, hdc, sc) into next ch, sl st in last 3 chs. Sl st into the next sc. Ch 6, sc in 2nd ch from hook. Sl st back up chain and jn with a sl st in the next sc. Fasten off.

Rooster:

~Body~
With a K hook:
Rnd 1: Ch 2. 6sc into the 2nd ch from hook. Jn with a sl st in the first hdc. (6 sc)
Rnd 2: (Jn new color with a sl st in same place as join if you’re chainging colors.) Ch 1, 2sc in each st around. Jn with a sl st in first sc. (12 sc)
Rnd 3: Ch 1, 3hdc in each st around. Jn with a sl st in first hdc. (36 hdc)
Rnd 4: Ch 1, (hdc in next 4 sts, 2hdc) around. Jn with a sl st in first hdc. (42 hdc)

~Tail~
With an F hook:
Ch 6, sl st in 2nd ch from hook an in last 4 chs. Ch 9, sl st in 2nd ch from hook and in last 7 chs. (Ch 11, sl st in 2nd ch from hook and in last 9 chs) twice. Sl st 3 times across the bottom back to the beginning chain. Fasten off.~Head~
Use an F hook. You’ll be working from the neck and then leaving a space for the beak, and then making the top of the head:
Ch 3, sc in 2nd ch from hook, sl st in first ch. Ch 7, (hdc, dc, hdc) in 2nd ch from hook, sl st in next ch, (hdc, dc, hdc) in next ch, sl st in next ch. Fasten off. The two unworkd chains will be where the beak will be placed.

~Beak~
With an F hook, ch 3, sl st in 2nd ch from hook, sc in next chain. Fasten off and sew onto head.~Legs~
With a K hook and leg color, ch 40. Fasten off. Leave enough yarn on each end of the chain to thread it through a button or bobble for decoration.

~Handle~
With a K hook again: Chain 60, jn with a sl st in the 30th ch from hook to make the handle. Join the bottom of the chain to the center of the leg-color chain strip by first threading it through the center of the rooster body. Knot it so that it will stay.

~Rainbow~
Use an F hook.
*Work in the back loops only of the rounds of the rainbow.
*Jn with a sl st in first sc at the end of each round.

Rnd 1: Ch 2, 6sc in 2nd ch from hook. (6sc)
Rnd 2: 2sc in each st around. (12sc)
Rnd 3: Ch 1, 3sc in each st around. Jn with a sl st in first hdc. (36 sc)
Rnd 4: Ch 1, (sc in next 4 sts, 2sc) around. Jn with a sl st in first sc. (42 sc)
Rnd 5: Ch 1, (sc in next 5 sts, 2sc) around. Jn with a sl st in first sc.
Rnd 6: Ch 1, (sc in next 6 ss, 2sc) around. Jn with a sl st in first sc. Fasten off leaving a tail long enough to sew rainbow together around the edges when you fold it in half. Feed the handle through the center of the rainbow, then fold it in half and sew it in place

~Clouds~
Make 4 with an F hook.
Ch 4, (hdc, 3dc, hdc) into 2nd ch from hook, sl st in next chain. (Dc, 3tr, dc, ch 2, sl st, hdc, 2dc, hdc) into last chain, pivoting work so that you can sl st into the middle chain. Then join the round with a sl st in very first sc.

~Sunflower~

The sunflower is if you are making the sunflower rooster version for a summertime charm rather than a lucky charm.
With an F hook:
Rnd 1: Ch 2, in 2nd ch from hook, (sc, ch 2, sc in 2nd ch from hook) 6 times. Jn with a sl st in first sc.
Rnd 2: In this rnd and next 2 rnds, you will only be working in the single crochet stitches that were done in the round. Not the ch-2-sc-in-2nd-ch-from-hook stitches. (Sc, ch 2, sc in 2nd ch from hook, sc) in each st around. Jn with a sl st in first sc.
Rnd 3: Switch to yellow and jn with a sl st in same st as join from Rnd 2. Ch 1. (Sc, ch 2, sc in 2nd ch from hook) in same st as join. (Sc, ch 2, sc in 2nd ch from hook, sc) in next st. *(Sc, ch 2, sc in 2nd ch from hook) in next st, (sc, ch 2, sc in 2nd ch from hook, sc) in next st. Repeat from * back around to first sc. Jn with a sl st in first sc.
Rnd 4: Ch 1, begining in same st as join, *(Sc, ch 2, sc in 2nd ch from hook) twice. (Sc, ch 2, sc in 2nd ch from hook, sc) in next st. Repeat from * around. Jn with a sl st in first sc and fasten off. Sew Sunflower to chain.
